FORMING MECHANISM.

Original application filed January 9, 1922, Serial No. 527,828. Divided and. this application filed.

December 28, 1323.

To all whom it may concern:

Be it known that I, "WALT R H. SERGENT, a citizen of the United States, and a resident of the city of Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in aForming Mechanism; and I do hereby declare that the following is va full l, clear, and exact description of the same, reference being .had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a forming mechanism for a caramel or candy wrapping machine in which the candy dough is fed to a rotary forming and cutter box from which the formed pieces of candy are projected to a wrapping wheel. This application is a division ofmy pending application for caramel wrapping machine, Serial No. 527,828., filed January 9th, 1922,

It is an object .of this invention to provide improved mechanism for forming and cutting the cubes or pieces of candy for feeding thesame into a wrapping wheel.

The invention comprises the .novel mechanisms and combinations hereinafter described and more particularly pointed out and defined in the appended claims. In .the accompanying drawings which illustrate the preferred form of this invention, and in which similar reference numerals refer to similar features in the different views.

On the drawings:

Figure l is a top plan view of the forming mechanism with parts omitted.

Figure 2 is a bottom plan view of said operating mechanism therefor with parts shown in section.

Figure 3 is a sectional View through a wiper that is used in connection with the forming box.

Figure t is a sectional View through the forming box, and the supporting framework therefor with a section of the wrapping wheel adjacent thereto.

Figure '5 is a sectional view through the wiper similar to Figure 3 with the parts, however, in different position.

As shown on the drawings:

Referring to the drawings, reference numoral 1 refers to an intermittently rotatable disk having a downwardly extending hub Serial N10. 683,189.

2, rotatably mounted in .a socket formed in a supporting bracket 3, which constitutes a part of the framework of the machine. The lower surface of the disk which is provided with a beveled gear 4, by means of which intermittent rotary movement may be imparted to the disk. The upper surface of the disk 3 is provided with radially extending blades 5 near the outer periphery. :In the present instance these blades are secured in grooves in the upper surface of the disk and are tapered toward their inner end to provide a cutting edge. These blades are spaced a distance equal to the length of the cube of candy desired and they are also spaced a short distance from the outer periphery of the disk .to provide a circumferential marginal space for a guard 6 which encircles the disk land forms in connection therewith, a mould or forming 'boX that prevents the candy dough from .escaping, which is fed into the forming box.

As the plastic dough .is fed upon the .cut ting diskl, and passes under the guard .6, .or in other words as it is fed into the forming box, it is first acted upon by .a .presser foot 7, which presses or partially forces the ,plastic dough between the blades 5, and as the disk is rotated, the dough is acted upon by a second ,presser foot 8 which completely presses the plastic dough into the moulds formed by the blades 5, and guard 6, and at the same time shears the formed cubes .of dough by pressing against the cutting edges,

of the blades 5., as shown in Figure 1. The presser foot .8 is so constructed that it will only come in direct contact with a single blade at a time and .to preserve the edges of the cutting blades, a fibrous insert 8 or other suitable substance, is fixed in a specia'lly provided groove in the presser foot upper surface of the disk 1 and are connected for simultaneous operation. One method of accomplishing this functionconsists in using .a pair of cross levers .9 and rigidly connecting the outer end of each to its respective presser foot- (see rigidly connecting the inner e. lever to a separate vertical 0 or shaft 10.

secured side by side to the ear casing of the machine; the lo ver enr. of each shaft projecting beyond its bearin and being provided with a gear segment 12 (Fig. 2). The two gear segments intermesh in the form of a toggle so that the two shafts l0 are'constrained to oscillate simultaneously. For the purpose of oscillating the shafts 10, a crank 13 is rigidly secured to one gear segment at one end and connected by an adjustable link mechanism 14 at its other end to a wrist pin 15 eccentrically formed upon a driving shaft 16 journaled in a bearing boss 17 forming a part of the rear wall or casing of the machine. The shaft 16 is continuously operated from the main driving shaft of the machine.

In order to scrape and cleanse the cutting blades, a specially constructed wiping mechanism has been provided, as shown in Figures l, 3 and The mechanism consists of a pair of jaw members 18 pivoted intermediate their ends upon a reciprocating block or plunger 19 slidably mounted in a guideway formed in a support 20 secured to the bracket 21, adjacent the forming box.

The front part of the guideway is enlarged to allow the rear ends of the aw members to expand so that the wiping elements 22 secured to the forward ends thereof may contract and embrace the cutting blades 5.

i For the purpose of thuswise expanding the away or rabbeted upon their forward inner sides. A pair of rollers 25 or the like, are

preferably positioned atthe inner corner of the enlarged 'guideway and the rear ends of the jaw members are beveled so that upon the inward movement of the reciprocating block or plunger 19, the beveled ends will readily ride up the rollers into the restricted guldeway, thus opening the jaw members against the tension of the spring 23. The

4 slidable block or plunger 19 is periodically reciprocated by means of a bell crank lever of the guideway.

26 connected by a link 27 (shown in dotted lines in Figures 3 and 5) to the sliding block 19 which is provided with a wrist pin projecting through a slot 28 in the lower wall It is evident that as the plunger 19 is reciprocated outwardly the wiping elements will pass on each side of the blade, and when the outward limit of movement hasbeen reached and when the lug 2% strikes the rear end of the blades, the rear ends of the jaw members will advance into he enlarged guideway which will allow them to expand and press the wipers 22 together so that upon the inward movement of the block 19, they will scrape the blades, and when the inward movement brings the wipers to the ends of the blades 5, the beveled ends of the jaws 18 will ride up the rollers 25 into the restricted guideway to expand the wipers for another operation. This operation will be repeated as each blade 5 comes to rest in front of the wiping mechanism. As the cutting disk rotates only the distance between two blades at each operation thereof, it is only necessary to locate the wiping mechanism in front of a blade when at rest, as each succeeding blade will come to rest at the same point. The crank 26 is connected by suitable means to the operating mechanism of the machine.

The formed and sheared cubes of candy are ejected from the forming boX by an ejector 29 (Fig. ,4) into a pocket of a-wrapping wheel 30, as is well-known in the art; the guard (3 beingsuitably cut away for such a purpose. As the operation of the foregoing described mechanism is well understood in the art, further description thereof is deemed unnecessary.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
